3rd Place: ThinkVoice lets you speak without moving your mouth by combining Grok Voice with brain-sensing technology. It understands the conversation, suggests what you might want to say next, and lets you select a response using subtle motor movements. Dan isaac yang Elith

2nd Place: Signal embeds followers’ bios, posts, and engagement into a living graph and A/B tests different launches using simulated populations of your following, so every post hits maximum engagement. @adibilawar @jasonlai150_ @SChen1249 @JeffreyZh0u

1st Place: Nova taught Grok to reverse-engineer binaries into clean C. Started with 262KB GameBoy ROMs, ended up rebuilding a 1995 car’s ECU runtime. @theoc____ @supratikp07 @henryzhangumich

Congratulations to the winners of the SpaceXAI Grokathon 2026. Here are the top 3 projects that were built in the 12 hours!

@Daniel_Farinax This is great! This should've been first place IMO

@Daniel_Farinax Brain sensing? Really? You can see he has a-d multiple choice answers and evertime he nods his head he just goes down the list.

@Daniel_Farinax This is 3rd place lol?

@Daniel_Farinax What you mean its 3rd lol what were the jury on 😭

@Daniel_Farinax “Guys remember the first place was chosen by popular vote”

In all seriousness, my son needs this tool - - there are tons of non-verbal kids who’d love the ability to speak what’s on their minds. My kiddos is mostly non verbal (he understandably gets so frustrated) with a rare genetic mutation, like lots of kids at I’d love a lead to connect with the folks who created this 🙏

@Daniel_Farinax I wonder if this ca be adapted to work with @neuralink cc:@djseo @ALScyborg

@Daniel_Farinax Isn't it just a motion sensor on the head to select from multiple texts which then converted vis tts. Or am I missing something.

@Daniel_Farinax wow that's crazy this is the winner

@Daniel_Farinax I see you @Daniel_Farinax

@Daniel_Farinax 3rd place is scary and impressive at the same time 😲

@Daniel_Farinax FYI : This is not using brain-sensing technology. It's using beta and gamma waves generated by movement in the face like blinking eye, nodding up and down. etc. Made couple of these myself. Great work!

@Daniel_Farinax How is this not 1st place

@Daniel_Farinax 🔥👏🏼🫶🏼

@Daniel_Farinax Surgically jacking something into my brain? ❌ This? ✅

@Daniel_Farinax It wont be long now. A brain to computer interface is almost here. Just think of the god like powers we will have when we no longer need to speak out loud or hear, to command a computer. It will be like telepathy. 🫤

@Daniel_Farinax A single nod means yes, two nods mean no...😹🐾🐈‍⬛

@Daniel_Farinax Dude built a brain-reading app that lets you talk without using your mouth in 12 hours… I felt as dumb as a socialist lmao 🤣🥲

@Daniel_Farinax 🤗🚀wow 🥇

@Daniel_Farinax This would get me into so much trouble.

@Daniel_Farinax GOAT my broooo @elithpalomino

@Daniel_Farinax Congrats @Daniel_Farinax!!! Really neat work

@Daniel_Farinax Let’s nod to scroll through predetermined answers for prepared questions and call it “brain sensing” 🤣🤣

@Daniel_Farinax how tf is this not first lol

@Daniel_Farinax Subvocalization from science fiction has arrived.

@Daniel_Farinax This one is very intresting .

@Daniel_Farinax Very nice. Are your head movements signals?

@Daniel_Farinax Woa, this is incredible! Feels good to see AI helping in such cases

@Daniel_Farinax way to go guys!

@Daniel_Farinax Wait, what?! How in the world does this work?

@Daniel_Farinax @Daniel_farinax @yangchasiu @elithpalomino can i ask what's that sensor you are using?

@Daniel_Farinax Great work👏🏽

@Daniel_Farinax This should be top 1
